Gear drive mechanism with sweeping rotation in two perpendicular axes

A gear drive mechanism for creating a sweeping rotation along two perpendicular axes, which are different in that they include:

• a horizontal channel cluster, a ring gear assembly, and a vertical channel cluster, in which
• the horizontal channel cluster includes:
• a body and cover of a horizontal channel gearbox are used to mount a 5-speed gear transmission assembly, including pairs of double-spring double halves gears that are engaged, which reduce loss, increase accuracy of the transmission, and reduce time. the response of a transmitter when reversing the motion,
• a ball bearing inner ring block is designed in a form of a shaft, threaded in an inner ring, when screwed with a gear shaft, has the effect of preventing the ball bearing from moving in an axial direction,
• a position sensor assembly is mounted on the gear shaft that meshes with the ring gear assembly, helping to determine the position of the rotation angle of the gear drive mechanism;
• the ring gear assembly includes:
• a gear ring with block structure machined with horizontal and vertical concentric circular hole system, fitted with concentric and eccentric rotating shafts, ball bearings, used to guide the gear ring details horizontally,
• a vertical channel rotating shaft, which has the effect of mounting the vertical channel assembly, creating vertical movement,
• a horizontal eccentric shaft is designed as an eccentric shaft, has two steps, a head of the horizontal eccentric shaft is designed in the form of a cone, with a straight slot used to adjust rotation of the shaft clockwise or counterclockwise, helping to adjust bearing. contact with the gear ring, a pea-slotted part is used to customize a mounting position of a shaft fixing screw, another end has an internal threaded tap to install a ring stop screw in the bearing,
• the concentric rotating shaft is designed in the form of a concentric shaft, with two steps, a head of the shaft is designed in the form of a cone, with a drilled bolt hole to fix a shaft position, helping to fix the bearing when in contact with the gear ring, another end has an internal threaded tap for mounting the ring stop screw in the bearing,
• a horizontal channel damper, with an internal threaded tap used to attach a shock absorber, limiting travel for a horizontal movement of the gear mechanism,
• a ball bearing inner ring block is designed as a shaft, a head of the shaft is designed in the form of a cone, which acts to block the inner ring of the bearing, and at the same time acts as a bushing for the eccentric rotating shaft detail when adjusting the bearing according to a vertical axis,
• the vertical eccentric shaft is designed as an eccentric shaft, with two steps, a head of the shaft is designed in the form of a cone, with a straight slot used to adjust rotation of the shaft clockwise or counterclockwise, helping to adjust bearing. contact with the rim;
• pea slotted part for customizing the mounting position of a shaft fixing screw;
• another end is threaded outside the shaft to install a nut,
• the vertical channel rotating shaft has an axial design, with a threaded tap at one end of the shaft used to mount a vertical channel fan gear, ball bearings, block the ring in the vertical channel, create a rotation axis for the vertical channel assembly,
• the vertical channel fan gear including gears, springs, rivet pins, and bevel pins made from stainless steel, a pair of double spring double halves is designed in the form of a fan, connected by a canopy pin and a spring, making the two halves of the gear always in a state of misalignment, helping to reduce the slip of the gear pair. when operating,
• the gear ring has a circular arc, the surface of which consists of teeth to match the horizontal channel cluster, two sides of the gear ring are guide profiles, which are finely machined to ensure roundness and high concentricity,
• A horizontal channel rotation stop and a vertical channel rotation block are designed with stops on two sides, used to limit the stroke of the gear ring;
• the vertical channel cluster includes:
• a body and cover of a vertical channel transmission gearbox is used to mount the 5-speed gear transmission assembly, consisting of pairs of double-spring double halves that engage, creating vertical rotation,
• a vertical channel mount is used to mount a vertical channel transmitter, vertical channel rotation stop, counterweight and angular velocity sensor device.
